Compressive hyperspectral sensing, open by design.
Photonics Open Projects designs smart compressive hyperspectral sensors that make spectral sensing accessible at the point of care when it matters, from classrooms and fablabs to industrial precision agriculture and health care.
Our solutions
ONE-PIX
A hyperspectral single pixel imaging kit: an open-source hardware add-on that turns a spectrometer into a hyperspectral camera, ideal for education, research and low-cost spectral data acquisition.
PRO-PIX
The ultimate hyperspectral camera for professionals: compressive sensing technology with high hardware and software reconfigurability, built for precision agriculture, food processing, geology and health care.
Services
From feasibility studies to instrumental development and proprietary algorithm integration, our team supports every stage of your hyperspectral sensor deployment, turning raw scenes into actionable data.
Application areas
Precision agriculture
Crop health, water stress and phenotyping from field-scale spectral maps.
Food processing
Sorting and quality control based on real spectral signatures, not visual inspection alone.
Geology
Mineral and material discrimination in the field or on the production line.
Health care
Non-invasive tissue and sample analysis built on the same compressive sensing core.

How single pixel imaging works
A series of patterns is projected onto the scene. A spectrometer measures the average reflected spectrum for each projection, and a reconstruction algorithm rebuilds the complete spectral dataset from all the spectra acquired, synchronized end-to-end by an onboard Raspberry Pi.
Vision as a common
